1. A computer-readable storage medium having stored thereon computer-executable instructions for causing a computer programmed thereby to perform a method comprising:

  • selecting a quantization level within a range of quantization levels, wherein the selecting accounts for non-monotonicity of quality measure as a function of quantization level within the range, wherein the selecting comprises;

    if the function is non-monotonic, selecting the quantization level in a first mode; and

    otherwise, selecting the quantization level in a mode other than the first mode; and

    quantizing audio information by the quantization level.
